I've tried the D-Box seat. Its more the same experience just like in USS ( Shrek 4D minor the water sprinkle effect). The idea is great but for Guardian of The Galaxy, the extraordinary moment was not there, felt  more like Ogawa chair to make u stay up for the whole movie. 

I believe if it was done on some 1st person view kind of movie or horror flick, it would be the best.


TLDR versyun: Dont waste your moolah on D-Box for this movie, maybe wait for upcoming movie like Lucy.
